Uses

Used in Aviation Industry:
4-Methyloctadecane is used as a component in the formulation of aviation base oils for [application reason] its high thermal stability and low pour point, which are crucial for maintaining the performance of aircraft engines under extreme temperature conditions.
Used in Lubricant Industry:
In the lubricant industry, 4-methyloctadecane is utilized as an additive to enhance the lubricating properties of various oils. Its low pour point ensures that the lubricant remains fluid even in cold temperatures, while its high thermal stability prevents degradation under high-temperature operating conditions.
Used in High-Temperature Applications:
Due to its excellent thermal stability, 4-methyloctadecane is also used in high-temperature applications such as heat transfer fluids, where it can maintain its performance without breaking down or causing deposits.
Used in Chemical Analysis:
4-Methyloctadecane is employed as a reference material in chemical analysis, particularly in the study of the influence of high temperatures on the properties of various substances, including aviation base oils. Its well-defined chemical structure and properties make it an ideal candidate for such comparative studies.

Check Digit Verification of cas no

The CAS Registry Mumber 10544-95-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,5,4 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 10544-95:
(7*1)+(6*0)+(5*5)+(4*4)+(3*4)+(2*9)+(1*5)=83
83 % 10 = 3
So 10544-95-3 is a valid CAS Registry Number.
